OK … now, hear me out … There actually is an answer to the “Which came first – the chicken or the egg?” controversy.
Some eons ago, the evolution of birds produced animals that were proto-chickens – birds that almost, but not quite, had the characteristics of modern chickens. Two proto-chickens mated and the embryo inside the egg which was laid by the female proto-chicken experienced one or more genetic mutations. When hatched, the first modern chicken emerged. This first modern chicken then mated with other proto-chickens, with the characteristics of the modern chicken being the dominant traits. Over time the proto-chicken traits faded away from the chicken species to where only modern chicken traits remained.
So, obviously it was the egg which came first.
